RE needs less action not more. What it needs are better controls. RE:4 as great as it was, had too many zombies. By the time I had gotten to chapter 3-4 I had killed what 100's of zombies? It just didn't matter anymore and they had lost their impact. Oh look, another 10 zombies...bam bam bam.
- Fewer zombies
- Increase their damage and consequences of them getting close to you
- Implement smoother 3rd person shooting mechanics. Get rid of tank controls. More like Uncharted without the cover mechanics. (Though you can keep the cover mechanics for enemies that can shoot back.)
